Find the derivative of 𝑦=𝑥^(9𝑒)^(8𝑥). y'=

To find the derivative of the given function \( y = x^{(9e)^{8x}} \), let's break it down step by step.

We have \( y = x^{(9e)^{8x}} \), which is an exponential function. We'll use logarithmic differentiation to differentiate this function since both the base and the exponent involve \(x\).

### Step 1: Take the natural logarithm of both sides
\[
\ln y = \ln\left(x^{(9e)^{8x}}\right)
\]
Using the logarithmic property \( \ln(a^b) = b \ln(a) \), we get:
\[
\ln y = (9e)^{8x} \ln(x)
\]

### Step 2: Differentiate both sides implicitly
We now differentiate both sides with respect to \(x\). Using the chain rule on the left-hand side:
\[
\frac{1}{y} \frac{dy}{dx} = \frac{d}{dx} \left[ (9e)^{8x} \ln(x) \right]
\]
Now we need to differentiate the right-hand side, which involves the product of two functions, \( (9e)^{8x} \) and \( \ln(x) \).

### Step 3: Differentiate the product
We'll apply the product rule: \( \frac{d}{dx}(uv) = u'v + uv' \), where \( u = (9e)^{8x} \) and \( v = \ln(x) \).

1. \( u = (9e)^{8x} \), so \( u' = (9e)^{8x} \cdot 8 \ln(9e) \) (since \( \frac{d}{dx} (a^{bx}) = a^{bx} \cdot b \ln(a) \)).
2. \( v = \ln(x) \), so \( v' = \frac{1}{x} \).

Applying the product rule:
\[
\frac{d}{dx} \left[ (9e)^{8x} \ln(x) \right] = (9e)^{8x} \cdot 8 \ln(9e) \cdot \ln(x) + (9e)^{8x} \cdot \frac{1}{x}
\]

### Step 4: Solve for \( \frac{dy}{dx} \)
Now multiply both sides of the equation by \( y \) to isolate \( \frac{dy}{dx} \):
\[
\frac{dy}{dx} = y \left[ (9e)^{8x} \cdot 8 \ln(9e) \cdot \ln(x) + (9e)^{8x} \cdot \frac{1}{x} \right]
\]
Since \( y = x^{(9e)^{8x}} \), substitute \( y \) back into the equation:
\[
\frac{dy}{dx} = x^{(9e)^{8x}} \left[ (9e)^{8x} \cdot 8 \ln(9e) \cdot \ln(x) + (9e)^{8x} \cdot \frac{1}{x} \right]
\]

This is the derivative of the given function.
